Key Dialogue
"DOCTOR: Yes, of course. A Sea Base."
"TEGAN: Must be some kind of research station."
"DOCTOR: No, no, it's a Sea Base. A rather special kind of undersea military colony. Help me get this open, would you? Armed with the sort of missiles that kill life but leave everything else intact."
